I've only taken a glance, but it appears to me that the labels can be
added without intimate knowledge of the guts of Octave.
You might begin by looking at contour.m and __contour__.m
Regarding your problems building, what OS are you using? and exactly
what was the syntax you used to configure Octave?
Ben
[Labitt, Bruce] Thanks for the tip on contour. I'll take a look at it.
I think I have solved the build problem. Although I had LDFLAGS
pointing to the correct directory, ld could not find the libraries. I
had to add a file to /etc/ld.so.conf/ to get ld to be able to find
lpcre. Then the linker could not find libfftw3 so I had to add a
LD_LIBRARY_PATH statement to tell it an additional place to look. I
don't know why it was so painful - but it is done. My OS is Scientific
Linux 5.2, a RHEL clone. The OS was a fresh install rather than an
incremental upgrade.

Bruce
